1. Read thoroughly all of the installation and op-eration instructions before attempting instal-lation.

2. If your stove doesn’t have any bricks, install the bricks as shown in figure 34 (also see fig-ure 18, page 12).

3. The unit must be set on a non-combustible surface, such as brick, ceramic tile, stone, or concrete and be at least 1 inch in thickness and 18 inches larger than the dimensions of the base as stated in the specifications, fig-ure 1. The non-combustible floor protection must extend at least 16 inches in front of the unit.

4. Install the blower assembly to the back of the unit as shown in figure 16. See figure 3 for

typical hot air hookup.

5. Use 6 inch stove pipe to connect the smoke outlet in the back of the stove to an aP-ProVeD CLaSS a CHIMney. Install only One connection to one flue. Make sure you use at least three metal screws at each joint connection, refer to figure 9.

6. Install a barometric draft control (field con-trol 6” RC/BT) as described and illustrated on page 7 and 9, also see figures 9, 10 & 11.

CHIMney InForMatIon

The chimney is one of the most important yet most neglected and misunderstood portions of any Sol-id Fuel Burning Installation. THE FURNACE SHALL nOt be COnneCteD tO the Chimney with Other heating DeViCes.

There are two types of Class “A” chimneys:1. Masonry with tile liner suitable for venting resi-

dential or building heating appliances. (See NFPA 211.)

2. Class “A” Chimney, listed or certified by a na-tionally recognized testing agency as suitable for venting residential or building heating applianc-es. If your masonry chimney has not been used for some time, have it inspected by a qualified person (building inspector, fire department per-

sonnel, etc.). If a listed or certified manufactured chimney is to be used, make certain it is installed in accordance with the manufacturer’s instruc-tions and all local and state codes. See Figure 5, Manufactured Chimney Installation and Figure 6 of Masonry Chimney (note roof clearance) in ac-cordance with NFPA 211.

CoMMon CHIMney ProBLeMS

In order to have a proper operating Solid Fuel Heat System, the chimney must be capable of providing the draft required.

In the Vapor-Fire Model 100 Furnace, the required draft is .04 to .06 water column (W.C.). This can be measured using a draft gauge.

If the chimney cannot supply this constant draft, the unit will not operate properly.

In all furnace installations using Vapor-Fire Model 100 furnaces, a barometric draft regulator must be used and properly adjusted for proper draft. Provided – Set to .06 W.C. by sliding wt. to #6 vertical.

REASONS for insufficient draft readings:

1. Leaky Chimney – Air leaking in around a loose fitting clean-out door, flue pipes not tight at the joints, improper plug openings, or defective ma-sonry.

2. Chimney Improper Height – Chimney does not extend through the roof to a sufficient height to promote sufficient draft or causes a down draft-ing condition to take place. See NFPA 211.

3. Obstructions in the chimney – Check prior to us-ing holding a mirror in chimney cleanout door. This will give an inside view of the chimney.

4. Trees or other topographical barriers – Impending the chimneys operation or causing a down draft condition to exist. This can also be caused by ad-jacent building or the roof of the same structure where the chimney is not high enough (Figure 7).

5. Chimney Size – Chimney is not properly sized to adequately fit the appliance. It is either too small or too large. Minimum chimney height – 14 foot. Minimum Diameter – 6 inches.

6. Chimney Offsets – Chimneys with offsets should not be used. They cause an obstruction to draft as well as a place for debris to collect.

7. Elbow Restrictions – The flue pipe is connected to the chimney with too many elbows reducing the draft the chimney can provide.

8. Multiple Venting – When more than one (1) devise vents into the same chimney flue.

When smoke rises into the chimney, it will rise in a spiraling path.

The most important thing to remember about chim-neys is their need for maintenance and cleaning. If chimneys are not cleaned on a regular basis, it ef-fects the draft, as well as make an attributing cause to a chimney fire.

The draft can be improved by using a chimney cone (figure 8) or by extending the height of the chimney and reducing the flue area. A cone or chimney exten-sion can be made by a local sheet metal shop.

A properly operating chimney will tend to reduce the amount of creosote that is left deposited.

WarnInG

LaCk oF enouGH aIr For ProPer CoMBuStIon

If your house is fairly well insulated and relatively air tight, it may be necessary for you to think of providing an additional source of fresh air into your house to eliminate the possibility of starving the wood burning stove of the necessary amount for good combustion.

If you have a clothes dryer, kitchen or a bathroom exhaust fans, or even a fireplace burning and is competing for the available combustion air which could cause improper combustion. This could result in some smoke backing up into your house.

You might need to look at installing an air to air exchanger or finding another way to get some fresh air to prevent the smoke back up.

For any questions feel free to call 1-800-358-2049.

Use approximate 45 degree adj. elbows for angled connections – NO HORIZONTAL PIPING.

InStaLLatIon

Barometric Draft Control field 6” RC/BT provided with your model 100 Vapor Fire Furnace. A draft reg-ulator is designed for insertion into a six (6) inch tee. Refer to Figure 9 and 11 for mounting of the baro-metric damper. It is recommended that the stove pipe be installed with the crimped end down so that if any creosote is formed, as a natural by-product of combustion, it will run back towards the furnace and not run through the joint to the outside of the smoke pipe. The section of pipe (tee) holding the draft regu-lator must be installed in either an angled or vertical direction.

The draft control can be positioned within its collar to an upright position.

It is essential that the draft regulator be located in the same room (pressure zone) as the furnace and as close as possible to the flue outlet.

After installation, make certain the draft control barometric regulator is upright and level. Tighten the screw to hold firmly in place. See Figure 10.

Refer to figures 14 and 16, place fan assembly on the fan housing base so that the holes in the brack-ets align with the bolts that are already in the base. Place the washers and nuts in place, but don’t tighten down the nuts yet. Next, attach the side panels with the metal screws that were provided. Then slide the bottom channel in place so that the holes align with the side panel holes and secure with metal screws (the holes are on each end of the channel). Do the same with the top channel and secure tightly.

Now slide the blower assembly housing towards the back of the main housing so that the base slides un-derneath the main housing, about 2-3 inches, mak-ing sure that the side panels are against the main housing hood and secure it with the metal screws. Make sure that the fan outlet lip slides into the felt lined square hole in the hood and forms a tight seal around the lip. Now tighten the nuts. Set the large cover in place so that the front lip slides into the slip joint in the back of the hood.

Place the air filters into the channels. Place the filter cover in place.

The completed assembly, without the fans, should look like the drawing in Figure 15.

norMaL autoMatIC oPeratIon

When power is turned on the furnace is cold, the draft will be closed. As the temperature in the fire box rises to approximately 100-120 degrees F., the automat-ic draft opens allowing combustion air to enter the fire chamber. As the temperature in the fire chamber rises, the automatic draft will begin its throttling pro-cess until it is completely closed, allowing maximum furnace idling. (When it reaches your desired setting)

As the outer heat exchanger temperature rises past 105 degrees F. The secondary fan (low speed) starts automatically and continues to operate until the fire burns down and the heat exchanger cools to approx-imately 90 degrees F. This is adjustable.

The primary fan (high speed) will turn on automati-cally provided the side jacket is at 105 degrees F whenever the remote room thermostat is calling for heat. The fan will also turn on automatically if the plenum temperature rises to the setting on the high

limit switch (set at approximately 220 degrees F.) and will continue to operate until the temperature of the plenum has cooled down to approximately 100 de-grees F. The high limit is set at approximately 250 de-grees F. and if this temperature is ever obtained, the electronic control will be entirely de-energized and the automatic draft controller will close. Conditions will remain in this state until plenum temperature has cooled with large fan running allowing the automatic high temperature cut-out switch to reset the control-ler.

If this condition ever occurs, check to see if the damper from the plenum is closed or for any obstruc-tions in the cool air return or in the air supply ducts and registers.

Indicating lights are furnished on the electric control to provide the following:

A. The RED THERMOCOUPLE LIGHT is on when there is an open circuit in the thermocouple. The automatic draft will remain CLOSED. Replace the thermocouple.

b. the green lOw temperature inDiCatOr LIGHT is on when the fire chamber is cold (70-100. F) and this indicates that the automatic draft damper is closed. To heat the fire chamber, start the fire with the ash pan door open, as soon as the GREEN LIGHT goes off CLOSE the ASH PAN door. The draft indicator lights will come on.

C. The DRAFT INDICATOR LIGHTS are on indicating that the various draft damper stages are open.

D. the reD high temperature inDiCating LIGHT & BEEPER are on when the temperature in the fire chamber is too high. If this condition occurs check the “to do” list located on the pro-cessor panel (circuit board).

E. If you are unable to solve the problem, call the factory 1-800-358-2049.

WooD BurnInG FaCtS

BE AWARE OF CREOSOTE “BUILD-UP” WHEN burning wOOD!

Wood burning equipment will give you trouble with creosote deposits under certain conditions, unless you are aware of these conditions and avoid them.

Creosote is a tarry liquid or solid resulting from the distilling of wood during the combustion process. It consists of a number of elements which condense and bake layer upon layer in the chimney flue.

Highly combustible in its solid and semi-liquid state, creosote is present in the gases given off by burning wood. Creosote may build up a considerable thick-ness on the interior surface of the chimney and flue pipes, considerably reducing their cross-sectional area.

Creosote condenses from the flue gases when the stack temperature drops below 250 degrees F. The amount of creosote deposited in the pipe and chim-ney is dependent on the amount of moisture in the flue gases, the temperature of the stack, and how completely the combustible elements in the flue gases have been burned in the combustion process. Most problems with creosote are due to poor chim-neys with low draft and cold walls and to a low rate of burning when heat is needed during the spring and fall months.

Moisture in the flue gases may be controlled by us-ing the driest wood possible, mixing small pieces with a very full load, and never using only large wood during mild weather when combustion is rela-tively slow.

BeSt WooD For BurnInG

Generally wood should be cut at least a year in ad-vance and properly split at that time.

This wood should also be stored out of the weather, if possible. If the wood is to remain outside, be sure to cover the top of the wood piles with sheets of metal, etc. This wood should be brought inside and stored there for at least two (2) weeks before it is fired to obtain top performance.

Soft woods burn at a faster rate per cord than do hard woods, and have less BTUs per cord.

Know what types of wood to burn. Wood is safe, clean and economical fuel. Freshly felled wood is not suitable fuel due to the moisture content of the wood. Well-seasoned wood is best for the proper produc-tion of heat. The following table will give you some relative values of the heating content of some of (the more readily available wood).

trouBLeSHootInG

IMPORTANT: Your Vapor-Fire Furnace is a controlled combustion solid fuel burning device that heats by the pyrolysis of wood at a slow rate. If you load the furnace and in a short period of time open the fire door, smoke will be expelled from the fire door. This is to be expected.

SMoke PuFFS FroM VaPor-FIre FurnaCe

A. Check the chimney draft. With a wood fire burn-ing, the chimney should supply .04” to .06” up-draft.

B. Check automatic draft control for proper opera-tion.

C. Check the smoke pipe and be sure it’s clean.

D. Chimney may be too low. Increase its height. Make sure the chimney is structurally sound.

E. Add more air to the furnace room. Your home may be so airtight, not enough oxygen is reach-ing the fire. Your heating contractor can do this. Refer to Figure 31.

F. Check the smoke pipe and make certain each joint is tight and the connections to the Vapor-Fire Furnace and chimney are air tight.

G. Check the ashes. Ash pan and fire compartment may be overloaded with ashes.

H. Check type of wood being burned. If too green or wet wood is being used, it may cause excessive smoking.

I. Check your chimney for down drafts. This is caused by air currents being deflected down the chimney from higher objects, such as trees , buildings, and hills. This problem can usually be corrected with an open vented chimney cap.

J. Make sure the chimney clean-out door is tightly closed.

K. If other fuel-burning devises are connected to the chimney, they may be causing draft problems. This must be corrected by your heating contrac-tor.

L. Remove any mesh from your chimney cap.

you are not reCeIVInG enouGH Heat FroM your FurnaCe

A. Make sure the pipe or duct from the Vapor-Fire Furnace, as well as the pipe connections, are air tight.

B. The cold air return of your forced air upflow furnace is blocked. NEVER PLACE SOLID OB-JECTS IN FRONT OF OR OVER THE COLD AIR returns in yOur hOme.

C. The cold air return of your forced air upflow fur-nace is inadequate. It may be necessary to in-crease its capacity.

D. If you don’t seem to get enough air circulation – pOssible Causes:

1. Air filter is dirty. Clean or replace air filter, as necessary.

2. Registers and grills are obstructed. Check supply pipe or damper positions. Check regis-ters and grills to make sure they are not closed or obstructed by carpet, draperies or furniture. Remove any obstructions.

E. Contact your dealer or installer for further techni-cal assistance.

SerVICe HIntS

A. Thermostat is not set correctly. Check adjust-ment.

B. No electric power to furnace. Check fuse or cir-cuit breaker. If fuse is blown, replace. If breaker is tripped, reset. Check to be sure shut off switch is “ON”.

C. Clean the inside of heat exchanger through opening on the front face of main housing unit. Remove plate covering the opening and scrape the inside of exchanger clean. Remove any loose soot through the flue collar in rear of stove.

A. Return (cold) air grills blocked. Check to make sure rugs and carpets are not covering return air grills.

B. Air filter is dirty. Clean or replace air filter, as nec-essary.

C. System is out of balance. Check supply pipe dampers or registers to balance system.

A. Blower motor and/or blower housing need tight-ening.

B. Air filter is dirty. Clean or replace air filter, as nec-essary.

SMoke PuFFS out tHrouGH DoorS

A. Chimney draft incorrect. Check chimney draft. With normal wood fire, chimney should draw .04 to .06” W.C. between furnace and barometric control.

B. Soot and creosote buildup in heat exchanger or chimney. Clean if necessary.

C. Chimney too low. Increase chimney height.

D. Obstruction in chimney. Check for obstruction such as loose mortar, bird nests, squirrels nests. Clean chimney to eliminate obstructions.

E. Not enough fresh air to furnace room. Check for obstructions in combustions air inlet.

F. Chimney diameter too large. A too cold a chimney will chill flue gases as they rise up the chimney. As this gas cools, it becomes heavy and other gases from the fire try to penetrate this heavy col-umn of cool air. This results in back puffing, poor combustion or burning, and may cause odors in your home.

G. Chimney clean-out door partially open. Make sure chimney clean-out door is tightly closed.

H. Other fuel burning device connected to same chimney. Make sure other device enters chimney at a higher level than your wood furnace. (It is necessary that the wood furnace have its own flue.)

I. Remove mesh from chimney cap. It is not de-signed for wood burning furnaces because it re-duces your updraft.

HoW tHe VaPor FIre eLeCtronIC DraFt ControL WorkS

reaD OVer the FOllOwing eXplanatiOns Very CareFully

1. When you first turn on the power – the 24 volt electronic control is energized, the controls high temperature siren sounds for only a short time, then after this, the control will automatically go to the low temperature setting which is when only the GREEN LIGHT is on.

2. When first starting a fire, you may open the ash pan door for a very short while until the control senses the heat which is being generated by the fire. Once the control senses the heat it will au-tomatically open the draft shutter. (ALL THREE LIGHTS WILL THEN BE ON). Allow the ash pan door to remain open for a short period of time to assure that the wood has properly ignited. NOW ClOse the ash pan DOOr anD the eleC-trOniC COntrOl will take OVer anD it will COntrOl the DraFt as neeDeD tO BURN THE WOOD, MAKE SURE THE ASH pan DOOr remains ClOseD anD that the latCh is hOOkeD thrOughOut the en-tire burn.

3. The electronic control has four different stages and the lights on the control indicate how much air is entering the fire chamber, for example as follows:

A. At start up, all three lights are on and also again at the end of the burn cycle, this indi-cates that the shutter is wide open.

B. As the fire gradually intensifies, only two lights are on which means that the control has automatically decreased the amount of air going into the fire chamber, now the shutter is partially closed.

C. As the temperature in the fire chamber con-tinues to rise, the control automatically closes so that only One light is on which means that the shutter is almost closed.

D. When the temperature in the fire chamber has reached it’s optimum level, there will be nO lights On. Now the shutter is completely closed, the stove is now what we call on the pilot burn and will continue like this until the fire cham-ber cools down and then the control again takes over and will adjust the shutter opening based on the fire chamber temperature.

4. the lOw tO high temperature knOb is used to adjust the total heat output of the vapor fire furnace, depending on what the temperature is outside.
